[GRASS-dev] Re: georectifier fixes for Debian

[Michael Barton]

Otto and Hamish,

I got a student here with Debian Ubuntu (Mepis) to try the --ui switch for
the i.group command in georectify.tcl. It seems to solve the problem of
i.group flashing on and off.

Thanks very much Hamish for suggesting it. It's in the cvs now. I'm copying
Markus so that he can backport it to 6.2.1

Michael
